128 Airbag system
How supplemental side airbags work
Side airbags deploy instantly and con help re­
duce the risk of upper torso injuries for occu­
pants who ore properly restrained.
Fig. 119 Inflated s ide airbags on left side of vehicle
When the system is triggered, the airbag is
filled with propellant gas and breaks through
a seam in the seat surface area marked "AIR­
BAG". It expands between the side trim panel
and the passenger . In order to help provide
this additional protection, the side airbag
must inflate within a fraction of a second at
very high speed and with great force. The sup­ plemental side airbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the sup­
plemental side airbag expands. This applies
especially to children
Q page 130, Child Safe­
ty.
Supplemental side airbags inflate between
the occupant and the door panel on the side
of the vehicle that is struck in certain side col­
lision
Q fig . 119.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the upper
part of the body.
A fine dust may develop when the airbag de­
ploys. This is normal and does not mean there
is a fire in the vehicle. Important safety instructions on the
side airbag system
Airbags ore only
supplemental restraints. Al­
ways properly wear safety belts and ride in a
proper seating position.
There is a lot that you and your passengers
must know and act accordingly to help the
safety belts and airbags do their job to pro­
vide supplemental protection.
A WARNING
An inflating side airbag can cause serious
or fatal injury. Improperly wearing safety
belts and improper seating positions in­
crease the risk of serious personal injury
and death whenever a vehicle is being
used.
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
- Always sit in an upright position and
never lean against the area where the
supplemental side airbag is located.
- Never let a child or anyone else rest
their head against the side trim panel
in the area where the supplemental
side airbag inflates.
-Always make sure that safety belts are worn correctly,
- Do not let anyone sitting in the front
seat put their hand or any other parts
of their body out of the window.
-Always make sure that the side airbag can inflate without interference.
- Never install seat covers or replace­ ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
deploy.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.

130 Child Safety
Child Safety
Important things to know
Introduction
The physical principles of what happens when
your vehicle is in a crash apply also to children
c::> page 102, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not
fully developed . In many respects children are
at greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully devel­
oped, they require restraint systems especial ­
ly designed for their size, weight, and body
structure . Many countries and all states of the
United States and provinces of Canada have
laws requiring the use of approved child re­
straint systems for infants and small children.
In a frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant will be more than 20 times the
weight of the child. This means the weight of
the child would suddenly be more than 260 pounds (120 kg). Under these conditions,
only an appropriate child restraint properly used can reduce the risk of serious injury.
Child restraints, like adult safety belts, must
be used properly to be effective. Used improp­
erly, they can increase the risk of serious in­
jury in an accident.
Consult the child safety seat manufacturer's instructions in order to be sure the seat is
right for your child's size
c::> page 133, Impor­
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the important information and WARNINGS
about child safety, Advanced Airbags, and the
installation of child restraints in this chapter.
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle and how they
work when infants and children in child re­
straints are on the front passenger seat. Be­
cause of the large amount of important infor- mation, we cannot repeat it all here. We urge
you to read the detailed information in this
owner's manual about airbags and the Ad­
vanced Airbag System in your vehicle and the
very important information about transport­ ing children on the front passenger seat.
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in­
fants and small children.
A WARNING
-
All vehicle occupants and especially chil­
dren must be restrained properly whenev­
er riding in a vehicle. An unrestrained or
improperly restrained child could be in­
jured by striking the interior or by being
ejected from the vehicle during a sudden maneuver or impact. An unrestrained or
improperly restrained child is also at great­
er risk of injury or death through contact
with an inflating airbag.
_& WARNING
Children on the front seat of any car even
with Advanced Airbags can be seriously in­
jured or even killed when an airbag in­
flates. A child in a rearward-facing child
safety seat installed on the front passen­
ger seat will be seriously injured and can
be killed if the front airbag inflates.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, door or roof.
- Never install a rearward facing child
safety seat on the front passenger seat
unless the
PASSENGER AIR BAG OFF
light comes on and stays on. If the PAS·
SENGER AIR BAG OFF
light does not
come on and stay on, have the airbag
system inspected immediately by your
Audi dealer.

Important safety instructions for us ing
child safety seats
Correct use of child safety seats substantially
reduces the risk of injury in an accident!
As the dr iver, you are responsible for the safe­
ty of everybody in the veh icle, especially ch il­
dren:
.. Always use the right child safety seat for
each child and always use it properly
r=;, page 135.
.. Always carefully fo llow the child safe ty seat
manufact urer's inst ruct ions on how to ro ute
the sa fe ty belt properly through the c hild
safety seat .
.. When using the vehicle safety belt to install
a child safety seat, you must first activate
the convertible locking retractor on the
safety belt to prevent the child safety seat
from mov ing
¢ page 138.
.. Push the ch ild safety seat down with your
full weight to get the safety be lt really tight
so that the seat cannot move fo rward o r
sideways more th an one inch
(2.5 cm).
Always remember: Even tho ugh your vehicle is
equipped with an Advan ced Airbag system, a
ch ild should always ride in the sea t properly
restrained for its age and s ize .
_& WARNING ,-= ~
Not using a child safety seat, using the
wrong child safety seat or improperly in­
stalling a ch ild restraint increases the risk
of ser ious personal injury and death.
- All vehicle occupants and especially chil­
dren must always be restrained properly
whenever riding i n a vehicle.
- An unrest rained or imp roper ly restrain­
ed ch ild ca n be injured or killed by be­
i ng th rown against the ins ide of the ve­
hicle or by being e jected from it during
a sudden maneuve r or impact.
- An unrest rained or improper ly res train ­
ed ch ild is at much greater risk of inj ury
or death by being struck by an inflating
airbag.

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and
80 lbs. (18 kg and 36 kg) who are less than 4
ft. 9 in . (57 inches/1 .45 meters) tall.
F ig . 122 Passen ger seat : child p roper ly rest ra in ed in a
booster sea t
The vehicle's safety belts alone will not fit
most children until they are at least 4
ft . 9 in .
(57 inches/1.45 meters) tall and weigh about
80 lbs .
(36 kg). Booster sea ts ra ise these chil­
dren up so that the safety belt will pass prop­
erly over the stronger parts of their bodies
and the safety belt can help protect them in a
crash.
.,. Do no t use the convertible locking retr actor
when using the vehicle's safety belt to re­ strain a child on a booster seat .
.. The shoulder be lt must lie as close to the
center of the child 's collar bone as possible
and must lie and snug on the upper body. It must never lie across the throat or neck . The
lap belt must lie across the pelvis and never
across the stomach or abdomen . Make sure
the belt lies flat and snug . P ull on the be lt
to t ighten if necessary.
Ch ildren up to at least 8 years old (over 40
lbs . or 18 kg) are best protected in child safe­
ty seats designed for the ir age and we ight. Ex­
perts say that the ske letal structu re, pa rticu­
l arly the pelvis, of these ch ildren is not fully
developed, and they m ust not use the vehicle
safety belts without a suitab le child restraint.
It is us ually best to put these childre n in ap­
propriate booster seats. Be sure the booster
seat meets all app licab le safety standards. Child S
afety 13 7
Booster seats ra ise the seating pos ition o f the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass
across the ch ild's body in the right p laces. The
routing of the belt over the ch ild's body is very
important for the child's protect ion, whether
o r not a booster seat is used.
Children who are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall can generally use the
vehicle's three point lap and shoulder belts .
Never use the lap belt port io n of the vehicle's
safety be lt alone to restra in any chi ld, regard­
less of how big the ch ild is. Always remember
that children do not have the prono unced pel­
vic struc ture required for the proper funct ion
of lap belt portion of the vehicle's three point
lap and shou lder belts. The child 's safety ab­
solutely requires that a lap belt portion of the
safety belt be fastened snugly and as low as poss ible around the pelvis. Never let the lap
belt portion of the safety belt pass over the
c hi ld 's stomach or abdomen.
In a crash , a irbags must inflate within a blink
of an eye and with considerable force. In order
to do its job, the a irbag needs room to i nflate
so that it will be the re to protect the occupant
as the occupant moves forward into the a ir­
bag .
A vehicle occupant who is out of posit ion and
too close to the a irbag gets in the way of an
inflating airbag . When an occupant is too
close, he or she will be st ruck violently and
will receive se rious or possibly even fat al in-
J LI ry .
In order for the airbag to offer protection, it is
importan t that all veh icle occupants, espec ial­
ly any children, who m ust be in t he front sea t
because of exceptional c ircumstances, be
properly restrained and as far away from the
airbag as possible. By keeping room between
the child's body and the front of the passen­ ger compartment, the a irbag can inflate com­
pletely and provide supplemental protection
in ce rtain frontal collisions .

Activating the convertible locking
retractor
Use the convertible locking retractor to se­
cure a child restraint.
A lways heed the child sa fety seat man ufactur­
er's instructions when ins talling a chi ld re­
straint in your vehicle . To activate the conver ­
tib le locking retractor:
., Place the child restrain t on a seat .
., Slow ly pull the be lt
all the wa y out.
., Route it around or through the chi ld re ­
stra int be lt path
c:> ,&. .
., Push the child safety seat down with your
full weight to get the safety belt rea lly t ight.
., In sert the be lt tongue into the buckle fo r
t h at seating posi tion.
., Gu ide the safety be lt back into the retracto r
u nt il the belt lies flat a nd snug on the chi ld
sa fe ty seat.
., You should hear a "clicking" noise as the
belt winds bac k into the ine rtia reel. Test the
conve rtible locking retractor by pull ing on
the be lt . You should no longer be able to
pull the belt out of the retractor. The con­
vertib le lock ing retractor is now act ivated. .,
Ma ke s ure that the red release button is fac ­
ing away from the child rest raint so that it
can be unbuckled q uick ly .
., Pull on the belt to make sure the safety be lt
is properly tight and fastened so that the
seat ca nnot move forward or sideways more
t han one inch (2.5 cm) .
A WARNING
Using the wrong child res traint o r an i m­
pr operly ins talled chi ld restraint can cause
se rious pe rsonal injury or death in a crash.
- Always ma ke sure that the safety belt re-
trac to r i s lo cked when insta lling a child
safety seat . An un locked safety bel t re­
tracto r cannot hold the child safety seat
in place dur ing no rma l dr iving o r in a
crash.
- Always buckle the child safety seat firmly
in place even if a ch ild is not sitt ing in it.
A loose child safety seat can fly around
during a sudden stop or in a crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright pos ition. Otherw ise, the seat­
back with the ch ild safety seat attached
to it could fly forward in the event of an
accident o r othe r emergency situation.

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru. Be sure to
switch ESC on again when you no longer need
less traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking . Apply steady pres ­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to
normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot overcome
th e laws of physics. This is especially im ­
portant on slippery or wet roads.
If the
systems begin acting to stabilize your ve­
hicle, you should immediately change
your speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligent technology 143
to take risks. Doing so will increase the
risk of a lo ss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot prevent colli­
sions.
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire si zes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working.
- If the ind icator lightD] orE (USA
